Correctables?

The stats are good. FWIW, channel 37 marked as (Other) is the DOCSIS 3.1 / OFDM channel. It is used for the delivery of their gigabit speeds. There is a known glitch with some makes / models of modem's firmware where the measuring mechanism incorrectly reads the power level, the SNR, and the bit errors for that channel. So it reads many errors when there really aren't. It's normal.

I don't see any "Uncorrectable" bit errors. They would be more of a problem than the corrected errors.

Are you actually experiencing any connectivity problems ? If not, don't sweat it.

Yes, I have been having intermittent issues. This was actually after a modem reset, right after it came online. I plugged the power cable back in to the modem at 12:34pm. It's an ARRIS SB8200, which other people have posted using the same modem, and have had nowhere near the amount of correctables. 

My internet will drop out for a minute here, minute there. Come back, and then do the same thing after a few minutes, or even a few hours. I have a simple ping monitor set up. Yesterday my connection was restored at 11:08am, and didn't drop out again until 8:54pm, but then it dropped out every few minutes until just after 10pm, making the internet pretty much unusable for anything besides scrolling Facebook. My son couldn't stay connected on his Xbox, my daughter was on a Zoom call that dropped, and my wife and I were watching Netflix and it started buffering every 30 seconds. 

It's random, I can't seem to get it to reproduce by doing anyhting on my end, but it keeps happening. I checked all the connections from the wall plate, even removing it and making sure the cable was snug to the plate, and then snug from the plate to the modem as well. I even preformed a factory reset on my Modem. Symptoms still happened with my laptop plugged directly into my modem, eliminating the rest of my network from the problem. It started Saturday night and persists currently. 

This had happened before and a technician came out and redid my connection at the pole and the problem was fixed, until now. I am not sure if it's the same cause, but I recall the tech saying something about too many correctables happening. That was also when I still had an Xfinity Xfi Gateway. I have had the ARRIS modem since February with zero issues until Saturday evening. 

O/k. Are there any error log entries being shown ? If so, please post them as well.

Ah, thank you. As I had said earlier, I had called Tech support last night and they had opened a ticket with the back end techs to check my connection. I was just trying to make sense of what I was looking at here. Whenever I googled the information, it always just led me to the Xfinity Forums, so I figured I would try and ask.

I guess my main question was what are the correctable/ uncorrectable entries about? Are they bad packets? Or is it something else?

The signal stats are o/k but the error log entries indicate that something is going on. Perhaps there is noise ingress into the line(s) somewhere.

There are other signal stat figures that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.

I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. They will be able to poll the CMTS to see whether or not everything is in the green zone, see your node / cable plant and modem health, and also see a history plot for the modem. You should get a reply here in your topic. Good luck !

Connection stabalized again, this is the current Line 37 entry

This is the event log: 

Also this is an updated status log, I was able to catch my internet acting up and get this in the middle of it: 

Hi @Eckx! Thanks for the screenshots of your logs. I agree with @EG. I can investigate your connectivity issues while checking to see if an additional IP Address is available for you. I've got your private message and will be replying shortly. 

Damaged / corrupted bits.
